Configuring an Asynchronous Port
5
Each asynchronous port can be configured for several different functions, giving the
PortMaster configuration more flexibility. However, each port can carry out only one
function at a time. For example, if a port receives a dial-in user login request, this port
cannot be used for anything else until the current session is terminated. The port is then
available for dial-out use or any other purpose specified when the port was configured.

Asynchronous Port Uses
The following examples describe various uses for asynchronous ports.
Connections between Offices. Office-to-office connections can be achieved with
either dial-up asynchronous connections or dial-up synchronous connections,
depending on your application. Chapter 15, “Using Office-to-Office Connections,” gives
an example of a dial-up asynchronous office-to-office connection. Chapter 12, “Using
ISDN BRI,” gives an example of a dial-up synchronous office-to-office connection.
Once a PortMaster is installed in each office and connected to the local Ethernet with an
AUI, 10Base2, or 10BaseT connector, one or more asynchronous serial ports can be
configured to dial another office or a set of offices when network traffic for the specified
location exists. The two most common configurations are a
